2. Description of the Related Art In recent years, an outside card reader installed outside a room allows the card information to enter the room, and an inside card reader installed inside the room allows the card information to be read to exit the room. A card management device for entering and leaving a room is known.

Further, the number of persons in the room is calculated from the card data read every time the person enters and leaves the room, and the entry is restricted when the number of people reaches the specified number, or the same card is handed to a third person, and a plurality of people illegally enter or leave the room. There are regulations on unauthorized entry and exit to prevent unauthorized use and to prevent multiple persons from using a card of the same data that has been illegally copied.

However, as a countermeasure against this, the card information read at the time of entering / leaving the room is transmitted to the upper control section, and this upper control section manages the data of the number of persons in the room and the entry / exit regulation. There is a problem that the card reader requires one upper control unit and the apparatus becomes large in size and cost, and the transmission processing time to the upper control unit is long and the processing speed is slow.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention provides a card management apparatus for entering / leaving a room, which does not increase in size even if the number of persons entering the room is restricted and unauthorized entry / exit control is attempted, and the cost is low and the processing speed is high. With the goal.

[0006]

SUMMARY OF THE INVENTION According to the present invention, an external card reader provided outside the room allows the card information to be read and allowed to enter the room, and an internal card reader installed inside the room reads the card information. A card management device for entering / leaving a room, which allows the user to leave the room, wherein the ID information of the card is stored when the card is read by the external card reader, and the card is stored when the card is read by the internal card reader. Of I
D When the control unit for erasing the information and the above-mentioned external card reader read the card when the ID information of the same card is already stored in the control unit, the entry is restricted, and when the card is read by the internal card reader, the control unit is controlled. An entry / exit control unit for restricting entry / exit when the ID information of the same card is not stored is provided.

Further, when the number of people entering the room stored in the control unit reaches the number of people entering the room based on the reading of the card by the external card reader when entering the room, the card for entering and leaving the room is provided with an entrance restricting means for restricting the subsequent entering of the room. It is a management device.

[0008]

According to the present invention, when the card information is read by the outside card reader to enter the room, the ID of the same card is entered in the control unit.
If the information is not stored, it is treated as a new entry, and the entry / exit control means stores the ID information of the card and allows entry. On the other hand, if the ID information of the same card has already been stored, the entry / exit control means determines that the third card is an unauthorized use attempting to enter the room by repeatedly using the same card and restricts entry. On the other hand, when the card information is read by the internal card reader and the user leaves the room, if the ID information of the same card is already stored in the control unit, it is treated as the same person leaving the room The ID information is erased to allow the user to leave the room. On the other hand, the same card I

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows, for example, an entrance / exit card management device that manages opening and closing of a laboratory door. As shown in FIG. 1, the entry / exit card management device includes a card 11 having ID information used as a card key, An external card reader 12 that allows handling of this card 11 and is installed outside the room
The internal card reader 13 installed inside the room, the control unit 14 that collectively controls and manages a plurality of these units, and the host computer 15 that manages the control data of the control unit 14.

The above-mentioned card 11 magnetically records personal ID information such as name and code number for identifying the user on the magnetic stripe of the card surface, and the main display items suitable for handling the card are displayed on the card surface. Is printed on.

Each of the card readers 12 and 13 for reading the magnetic data of the card 11 has a card 1 at the card insertion slot 16.
When 1 is inserted, the ID information recorded on the magnetic stripe of the card 11 is read, the read ID information is checked by the control unit 14, and a control signal corresponding to the read data is output to the door lock unit. Then lock or unlock the door.

FIG. 2 is a block diagram of the control circuit of the control unit 14. The CPU 21 controls each circuit device according to a program stored in the ROM 22, and the control data is stored in the RAM.
It is readable and stored at 23.

The timer 24 measures the current time and stores the use time at the time of entry into the card data table 25 of the RAM 23 as entry auxiliary data together with the card information. In this card data table 25, when the ID information of the card 11 is read by the outer card reader 12 when entering the room, the CPU 21 stores the read card ID information and entry time of the card in the RAM 23.
The stored entry data is collated and checked for each entry and exit to manage entry and exit.

As a result, even if a plurality of persons illegally repeatedly use the same card, or a third person tries to enter the room by using a duplicate card, the same data is already stored. It is judged that it is used and the entry is regulated, and unauthorized entry is surely prevented.

When the ID information of the card 11 is read by the internal card reader 13 at the time of leaving the room, the CPU 21 reads the card information and the leaving time of the read card and the data of the card data table 25 stored and managed at the time of entering the room. If the collation is confirmed and the same data is collated and confirmed, it is judged that the room has been normally exited and the room is allowed to exit. Further, at this time, the ID information of the card stored at the time of entering the room is not required to be stored, so it is deleted, and only the data of the person in the room is stored and managed. As a result, even if a plurality of people illegally repeatedly use the same card, or a third party tries to leave the room by using a duplicate card, the same data has been deleted, so the CPU 21 determines that the illegal card is used and leaves the room. Regulate and reliably prevent unauthorized leaving behavior.

Further, the CPU 21 predetermines the maximum number of people who can stay in a room, and when the number of people in the room reaches the maximum number of people in the room based on the increasing / decreasing entry / exit data, the CPU 21 restricts the subsequent entering of the room and becomes excessive. It can be managed properly so as not to leave the room.

The door lock unit 26 uses a lock mechanism such as an electric lock and locks and unlocks the opening and closing of the door based on a control signal from the CPU 21. Further, the entry / exit detection sensor S is provided at the entrance of the door and detects and confirms passage of the entering person and the leaving person each time the entering / leaving card is used.

The processing operation of the room entrance / exit card management device thus configured will be described with reference to the flowchart of FIG. Now, when the card 11 is inserted into the outside card reader 12 of the laboratory, the card information is read by this outside card reader 12, and if the read card information is correct, then it is the same as the card information of the entering user. It is checked whether or not the card information of No. is already stored in the card data table 25 (steps n1 to n4).

At this time, if the same card information is not stored and it is determined that a new card has been inserted, the card information and entry time are stored in the card data table 25 to permit entry (steps n5 to n6). ).

By the way, when an improper card 11 is inserted, normal data cannot be read, and therefore entry and exit are restricted. Furthermore, when entering the room, the same card information as the user's card information is already stored in the card data table 25.
If it is stored in, the same card information is judged to be an illegal act of entering the room repeatedly by a third party, and entry is restricted. If the same card information as the user's card information is not stored in the card data table 25 when leaving the room, it is determined that the same card information is repeatedly used by a third person, and it is determined that the user is leaving the room. Restrict (step n7).

On the other hand, when the card 11 is inserted into the internal card reader 12 when leaving the room and the ID information of the card 11 is read, the CPU 21 reads the ID of the read card.
Information and card data table 2 stored and managed when entering the room
When it is verified that the data is stored and managed in the card data table 25, for example, as shown in the card data table 25 of FIG. 2, the first to nth cards are checked. If one of the ID information is checked and the passage of the entry time and the exit time is judged to be proper (step n8), it is determined that the room is normally exited, and the ID information of the card 11 stored at the time of entry is used as card data. Erase from the table 25 and allow exit (steps n9 to n)
Ten).

Further, in this case, the CPU 21 predetermines the limit number of people in the room, and when the number of people in the room reaches the limit number of people in the room based on the entry / exit data, the CPU 21 controls the subsequent entry of the room so as not to excessively stay in the room. As a result, the number of people in the room can be maintained at an appropriate number of people.

As described above, since one control unit can control and manage a plurality of pairs of card readers, which are the outer card reader and the inner card reader for each room, the device can be downsized and the cost can be reduced. The control unit can manage data for one room entering and leaving. Therefore, the processing efficiency of data is improved, and high-speed data processing can be performed. In addition, since it is possible to regulate unauthorized use when entering and leaving the room,
It can be used as a high security room. Furthermore, since the number of people entering the room can be accurately controlled, the number of people currently in the room,
The usage status and the number of people in the room can be managed accurately, and reliable room entry / exit management is possible.

In the correspondence between the present invention and the configuration of the above-described embodiment, the entry / exit control means and the entry control means of the present invention correspond to the CPU 21 and the door lock portion 26 of the embodiment, but the present invention is described above. It is not limited to the configuration of the embodiment.
